Treatment planning of stereotactic radiosurgery for single brain metastases: impact of leaf width

Emmy Lamers (Lid Lectoraat)

Purpose/objective: Stereotactic radiosurgery of brain metastases requires highly conformal dose distributions. Besides beams setup, characteristics of the linear accelerator collimator may also play a role. In this study we compared the impact of leaf width on the dose outside the target for stereotactic …

Reconstruction of high-resolution 3D dose from matrix measurements: error detection capability of the COMPASS correction kernel method

Godart, Jeremy; Korevaar, E.W.; Visser, Ruurd; Wauben, D.J.L.; van 't Veld, Aart A.

The COMPASS system (IBADosimetry) is a quality assurance (QA) tool which reconstructs 3D doses inside a phantom or a patient CT. The dose is predicted according to the RT plan with a correction derived from 2D measurements of a matrix detector. This correction method is necessary since a direct reconstruction …

Applicability of the Matrixx detector combined with the compass system to detect leaf positioning errors of an elekta beam modulator

Godart, Jeremy; Korevaar, Erik.W.; Wauben, D.J.L.; Visser, Ruurd; van 't Veld, Aart A.

This study explores the capability of the COMPASS system (IBA Dosimetry, Germany) to detect leaf positioning errors of a high resolution MLC with 4mm leaf width using a lower resolution (7.62mm detector spacing) 2D matrix of ionisation chambers
